| * selinux: use the kernel headers when building scripts/selinuxPaul Moore2016-12-214-2/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 3322d0d64f4e ("selinux: keep SELinux in sync with new capability definitions") added a check on the defined capabilities without explicitly including the capability header file which caused problems when building genheaders for users of clang/llvm. Resolve this by using the kernel headers when building genheaders, which is arguably the right thing to do regardless, and explicitly including the kernel's capability.h header file in classmap.h. We also update the mdp build, even though it wasn't causing an error we really should be using the headers from the kernel we are building.

It also doesn't check for this failure, so it busy-loops calling wgetch(NULL) which immediately returns -1. The additions in the offset calculations also don't match the intended size of the window. Limit the window size and calculate the offset similarly to show_scroll_win().

When the modules referring to exported symbols are built, there is an existing warning for missing CRC, but it's not always the case such any such module will be built, and in any case it is useful to get a warning at the source.

Currently the empty input file is an archive containing nothing, however this causes the gold linker to segfault. I have opened a bug against gold https://sourceware.org/bugzilla/show_bug.cgi?id=20767 However this can be worked around by assembling an empty file to link with instead. The resulting lib-ksyms.o is slightly larger (seemingly due to empty .text, .data, .bss setions added), but final linked output should not be changed.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | kallsyms generation is not foolproof, due to some linkers adding symbols (e.g., branch trampolines) when a binary size changes. Have it attempt a 3rd pass automatically if the kallsyms size changes in the 2nd pass. This allows powerpc64 allyesconfig to build without adding another pass when it's not required. This can be solved other ways by directing the linker not to add labels on branch stubs, or to move kallsyms near the end of the image. The former is undesirable for debugging/tracing, and the latter is a more significant change that requires more testing and review.

This requires the inline kernel-doc comments to have the opening and closing comment markers (/** and */ respectively) on lines of their own, even for short comments. For example: /** * struct foo - struct documentation */ struct foo { /** * @bar: member documentation */ int bar; }; Add support for one line inline comments: /** * struct foo - struct documentation */ struct foo { /** @bar: member documentation */ int bar; }; Note that mixing of the two in one doc comment is not allowed; either both comment markers must be on lines of their own, or both must be on the one line. This limitation keeps both the comments more uniform, and kernel-doc less complicated.
